CSDb - Growth of the past decennium
I'm working on an updated release of CSDb - Quantify me 2012 - 10 years of CSDb
The year 2000 is the all time low in number of releases released (as registered in CSDb). We know CSDb started in 2001, and proper in 2002. So it's worthwhile to start the counter from 2000 on and look at the growth in release till now. That's 12 years. The first 6 years an average of 882 releases a year, the second half 1055 releases a year. A slow but significant growth. Also, it seems CSDb has shown a linear cumulative growth in those 12 years.
11624 releases in the period 2000-2011. The start of CSDb has probably been very important for this growth, as it has also become a platform to release everything new immediately for many a scener. |

Quoting Mr. MouseInstead of just looking at the graph, read the text in the first post.
"here's a graph, dont look at it, read the text instead, that's where the info is at!"
Quoting Mr. MouseI do have such another graph, though, but the straight line says all, don't it.
the straight line tells me nothing changed in the last 10 years, that we had more or less the exact same amount of releases every year.
and as groepaz posted, http://noname.c64.org/csdb/stats/entrystat.php?type=release&day.. is the interesting graph. if we could have one of those based on release year.... ;) |

It's true that people could feel less inclined to add stuff, on the other hand, there are just a few people that have added a lot, their dedicated seems supernatural, and might not falter to easily.
Burglar, like I said in the post : "The first 6 years an average of 882 releases a year, the second half 1055 releases a year. A slow but significant growth."
If I test the difference between the first 6 years, and the second 6 years, there is a significant increase in releases per year the second half. So there is some growth, and the line is indeed not completely straight. It is up to everyone to release more stuff, and not more or less the same each year as was currently the case ;-)
As for the graph per release year, you may as well take this one I did in 2010.
I have an updated one, but the curve is visually identical. |

Keep in mind that 2000+ is pretty much complete on CSDb, while a hell lot of stuff is still missing from earlier times, especially the 80's.

The data shows that after a peak in 2005, 2006, where practically everything added to CSDb was released in an earlier year, the portion of releases added to the CSDb that were not created in the year they were registered in CSDb is becoming smaller. Like I said, that is probably due to a saturation effect. The pool of available releases NOT added to CSDb yet is decreasing as more is added. And it seems people will find it harder and harder to find anything old that is not yet in. I don't think people are becoming lazy and quit adding old stuff, as those that rank the top as uploaders/submitters have been really thorough and dedicated.
There comes a time when you reach the actual number of releases. The graph above already shows that the 80s is well accounted for. |

It is evident from this figure that 2006 was the peak year, with 18000+ entries in CSDb (15000+ were not dated as released in 2006). However, the number of entries declined each year since, with last year the lowest at +/- 7000 (4482 of those were dated as releases in other years than 2011).
The afore mentioned saturation effect is suggested by the following figure:
The last years, the proportion of releases submitted that were created in earlier years is declining. From 2006 on, between 1500 and 2500 releases each year were added without a release year/date. In total 13% of releases in CSDb have no date.

Nice! Yes, I note that the graph with C64 in number of releases matches the one I got in 2010, and get in 2012, in terms of shape. However, the analysis of CSDb has almost a 5 fold higher number of releases accounted for. And, as stated in the text there, most of the entries in pouet are actually from CSDb. Cool stuff though! |

Curious, that article from subsquare.com lumps Amiga & Atari together and seems to completely ignore Atari 8bit? In fact, appears c64 is the only 8bit covered in the article. |

The above figure shows the top 10 release types of the past decennium, including the year 2000. It plots the running average number of releases per year, by top 10 type. The afore mentioned slow growth of yearly releases seems to be coming from Graphics releases, an early growth in Music releases (and now seemingly hitting a plateau), and growth in One-file demos the last period. There is also some increase in Games and Other Platform C64 Tools. Cracks are released at more or less a steady stream. Of note: the number of Diskmags only shows decline.
The following figure shows it stratified by two periods of 6 years.
